Coronal mass ejection is an interesting phenomenon that occurs in the outermost atmosphere of the sun. The event involved the ejection of charged particles as well as a significant magnetic field into space. This phenomenon is somewhat mysterious, so it makes scientists excited to do some research.
Observations about the sun have always been the concern of astronomers and space researchers. Along with the advancement of technology and devices, scientists have revealed various interesting phenomena at the center of the solar system.

One of the mysterious events that has caught the attention of researchers is the “mass ejection”. In English this phenomenon is popularly known as “coronal mass ejectionor CME.
Corona Mass Ejection, Mysterious Phenomenon
As previously stated, coronal mass ejection occurs at the center of the solar system. The event occurs when most of the charged particles and magnetic fields on the surface of the sun are released into space.
This is the result of instability in the sun’s outer atmosphere called the corona. The corona itself is the outer layer of the sun which has a very high temperature and extends far beyond its surface.
Meanwhile, the surface of the sun has a complex magnetic field. Over time it can cause an accumulation or buildup of energy in the corona. When the energy reaches an unbearable level, mass ejection occurs.
During this event, there are millions to billions of tons of charged particles ejected at thousands of km/second. Coronal mass ejection is an interesting phenomenon for scientists for many reasons.
The first reason, through study coronal mass ejection, scientists can understand the nature and behavior of the sun. This phenomenon helps to recognize the cycle of solar activity to understand how the magnetic field interacts.
The mass ejection on the surface of the sun can in fact affect space weather. This then becomes the second reason why scientists are active in conducting various studies. Because by knowing the details of events, they are able to predict future weather waves.
In addition, observations of coronal mass ejections help identify similar phenomena in stars throughout the galaxy. The results can provide valuable insights into both life and the evolution of stars in the universe.
Impact of Coronal Mass Ejection on Earth
The ejection of mass on the surface of the sun can have a large impact on the solar system. When the ejected masses reach Earth, they can interact with the planet’s magnetic field. Then it causes a number of things that trigger positive and negative impacts as follows.
1. Aurora
The only positive effect of a coronal mass ejection is that it causes a stunning visual effect in the sky. Especially in the polar regions of the earth.

When the charged particles from the ejected mass meet the atmosphere, they cause beautiful and colorful lights. This phenomenon is more popular with the term aurora or northern and southern lights.
2. Communication and Navigation Disturbances
If the mass ejection reaches the earth, highly charged particles can interfere with radio waves and satellite navigation. The signals that satellites transmit can bounce or bend due to charged particles in the atmosphere. Thus triggering a loss of signal and an unstable connection.
3. Electrical Interference
Highly charged particles that are ejected and interact in a magnetic field can induce electric currents in transmission lines.
This phenomenon causes an excessive surge in electric current. So that there is a risk of damaging transformers and electrical equipment causing blackouts on a large scale.
4. Radiation Threats for Satellites and Astronauts
Coronal mass ejections can cause an increase in radiation in space. This will threaten the position of astronauts who are on deep space missions. Because they have to deal with high radiation risks during this ejection event.
5. Health problems
Although the earth’s atmosphere has an effective protection against energetic particles from outer space. That doesn’t mean it won’t be affected by mass ejection events. One of them is an indication of a large mass ejection event that has an impact on human health.

Several studies have found a correlation between high mass ejection activity and an increase in health complaints. Including dizziness, excessive headaches, high blood pressure, to sleep disturbances.
6. Damage to Space Technology
Mass ejection can also cause disruption to communication and meteorological systems. A technology that relies on sensitive electronic systems and can be damaged by direct exposure to highly charged particles.
Thus a review of the corona mass ejection that can occur at any time. Complete with a number of impacts due to this phenomenon. Hopefully, this information can provide a better understanding of mysterious events in outer space. (R10/HR-Online)
